In one of the few mayoral races in recent memory without a clear front-runner, candidates Lori Lightfoot and Toni Preckwinkle led the 14-candidate field and are heading to a runoff election for mayor in April. (In Chicago’s runoff system, if no candidate receives a majority of votes, the top two vote-getters face each other again.) At the ward level, several incumbent aldermen lost their seats to political newcomers and 14 more races—plus the city treasurer’s spot—will head to a runoff election. Several wards, like the 20th and 25th, saw crowded fields where a longtime incumbent was taken out of the running due to legal woes.
